However, in the case of underwater cleaning, there is an aspect that the cost must rise due to the watertight structure and waterproof measures as expected. As a result, there have been cases where the adoption of an underwater cleaning device was withheld due to cost problems, while recognizing the effect of the underwater cleaning method.

に噴射されることとなる。In the air cleaning method of the present invention, as shown in FIG. 1, the injection port 12 installed in the nozzle port 11 of the cleaning nozzle 10.
Since the high-pressure water is jetted from the inside, the inside of the nozzle port 11 can be highly negativeized, and the low-pressure water and the air flow can be introduced into the nozzle port 11 from the outside by using the negative pressure as a suction force. As a result, low-pressure water and gas are caught in high-pressure water,
The high-pressure jet water having a high degree of kinetic energy is jetted onto the object to be cleaned.

する。The high-pressure jet water jetted from the washing nozzle 10 naturally forms a central washing region A where the high-pressure jet water flow collides with the object to be washed to remove the dirt adhering thereto. However, a peripheral cleaning region B is formed in a certain range around the central cleaning portion due to high-pressure diffuse reflection of the high-pressure jet water flow that has violently collided with the object to be cleaned (FIG. 2). In this portion B, the fluid that is diffusely reflected by the high pressure propagates on the surface of the object to be cleaned and causes a strong interfacial flow, so that it also acts as a cleaning force.

To be enhanced. Further, if the effective cleaning distance from the cleaning nozzle 10 when simply ejecting high-pressure water is D,
The effective distance is increased by as much as 50% according to the invention.

洗浄効果を得ることができる。In the air cleaning method of the present invention, the most remarkable effect can be obtained when the cleaning is carried out in a state where the pressure applied to the high pressure water and the amount of water are balanced. For example, Akg / cm 2
The best cleaning effect is obtained when low pressure water of B liter per minute is supplied to the high pressure water of the injection pressure of, and when it is lower than B liter, the cleaning ability of the high pressure water can be satisfied due to lack of water volume. On the other hand, in the case of B liter or more, the energy of the high pressure water is lost to the weight of water, resulting in an unsatisfactory result. Therefore, the maximum cleaning effect can be obtained by adjusting the pressure and the amount of water so that the maximum acting force is obtained in the central cleaning area A.
